Abstract
Apparatus for use in receiving input signals through order wires; at least one of the input signals is a specific signal including an input control signal indicative of supply of the specific signal to either a telephone set (6) or a facsimile set (15). A processing circuit processes (2) the input signals into an input single signal; an input detecting circuit (3) detects the input control signal in the input single signal; a judging circuit (14) judges whether the input control signal indicates supply of the input single signal to the telephone set, or to the facsimile set and produces an input connection signal; and a connection unit (20) connects the processing circuit to the telephone set and to the facsimile set when the input connection signal indicates the telephone set and the facsimile set, respectively. It is also possible to use the apparatus to transmit output signals produced by the telephone set and the facsimile set through the order wires.
